We analyzed the Dingri MS6.8 earthquake as a case study. A multivariate dataset comprising land surface temperature, net surface solar radiation, and other variables in the study area was constructed. After decomposing the time series of each variable, the generalized extreme studentized deviate(GESD) algorithm was applied to extract anomaly signals. The weighted averaging method was then employed to integrate multi-variable anomaly extraction results. The results indicate that the thermal infrared anomalies in the half-year period before the Dingri MS6.8 earthquake exhibited a cyclic change pattern of "emergence-enhancement-weakening". The Dingri MS6.8 earthquake occurred 100 days after the maximum value of the anomalies appeared, and the main direction of the anomalies was NW-SE, forming an approximately 45° angle with the Dengmo Co fault, which is the seismogenic structure of this earthquake.
